目的：分析匣形曲（box loop）正轴的临床效果，并比较“0.014”与“0.016”澳丝弯制的匣形曲对牙根吸收的影响有无差异。方法：选取20例斜轴牙病例，分为两组，每组10例，分别运用“0.014”和“0.016”澳丝弯制的匣形曲对其矫正，拍摄斜轴牙矫正前后根尖片，以改良根吸收分级法分析评估斜轴牙治疗前后牙根形态变化，并进行统计学分析。结果：①匣形曲可以有效正轴，“0.014”组平均3个月，“0.016”组平均2.5个月；②两组病例各有1例发生轻度根吸收，发生率均为10％，两组牙根吸收率的差异无统计学意义，两组病例治疗前后牙根形态差异无统计学意义(P>0.05)。结论：匣形曲可以安全有效的矫正斜轴牙。
目的：分析匣形麯（box loop）正軸的臨床效果，併比較“0.014”與“0.016”澳絲彎製的匣形麯對牙根吸收的影響有無差異。方法：選取20例斜軸牙病例，分為兩組，每組10例，分彆運用“0.014”和“0.016”澳絲彎製的匣形麯對其矯正，拍攝斜軸牙矯正前後根尖片，以改良根吸收分級法分析評估斜軸牙治療前後牙根形態變化，併進行統計學分析。結果：①匣形麯可以有效正軸，“0.014”組平均3箇月，“0.016”組平均2.5箇月；②兩組病例各有1例髮生輕度根吸收，髮生率均為10％，兩組牙根吸收率的差異無統計學意義，兩組病例治療前後牙根形態差異無統計學意義(P>0.05)。結論：匣形麯可以安全有效的矯正斜軸牙。

Objective:To evaluate the therapeutic effect of box loop on uprighting axiversion and compare the difference between the root resorption rate and grade of “0.014” and “0.016” box loop. Methods: 20 cases of axiversion were selected and divided into two equal groups using “0.014” and “0.016” box loop respectively. The apical resorption was measured by periapical film and statistically analyzed. Results: ①Box loop was effective in uprighting axiversion, the average treatment time of two groups were 3 months (“0.014”) and 2.5 months (“0.016”). ②One case of each group had light root resoption after treatment , but there was no statistical difference in the root resorption grade of two groups(P > 0.05). Conclusion: Box loop can be safe and effective in uprighting axiversion.
